Lets us learn Differentiability
We have already defined the derivative of a function f(x) at a particular point 'a' and derivative of f(x) in general for the variable x as f
(a) and f
(x) respectively. The restriction in both the cases is that 'the limit must exist' differentiability of a function.
If
does not exist, then we say that the function is not differentiable.
If the above limit exists, we say the function f(x) is differentiable.
